9、he International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical commit
10、tee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotech
11、nical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approva
12、l by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 3019 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 3019-2 was

Pumps convert mechanical power into hydraulic fluid power, while motors convert hydraulic fluid power into mechanical power. This p
16、art of ISO 3019 provides a minimum number of flanges and shaft sizes to cover probable present and future requirements (short and long flange spigot options are included), dimensional interchangeability of flange and shaft end mountings, flange and spigot dimensions allowing for recommended sealing
17、arrangements when sealing is required between a flange and its mating housing (see annex A), and identification codes for flanges and shaft ends that can be used separately or in combination.INTERNATIONAL STANDARD ISO 3019-2:2001(E) ISO 1002 All rights rsedevre 1 Hydraulic fluid power Dimensions and
18、 identification code for mounting flanges and shaft ends of displacement pumps and motors Part 2: Metric series 1 Scope This part of ISO 3019 establishes a metric series of mounting flanges and shaft ends for positive-displacement, rotary hydraulic fluid power pumps and motors. It specifies sizes an
